metaphacts contributes new dataset to QALD2017 challenge

DIESEL & HOBBIT Logos May 30, 2017 - The three DIESEL project partners – metaphacts, Zazuko and the University of Leipzig – teamed up with the HOBBIT project to provide a new dataset for the QALD7 challenge, which is taking place at the Extended Semantic Web Conference 2017. The key challenge for QALD7 – Question Answering over Linked Data – is to translate a user's information needs such that they can be evaluated and answered using standard Semantic Web query processing and inferencing techniques.

The dataset created by the partners serves as the 4th task within the QALD7 challenge. For this task, Wikidata, a public data source, is used as a target repository. The teams taking part in the challenge use Wikidata to answer 100 cross-domain factual questions. The collaboration between the DIESEL and HOBBIT project partners resulted in the creation of the metadata, the set of answers available for each question, as well as SPARQL queries executable over the Wikidata query service. The Docker image holding an installation of the Blazegraph Wikidata query service used for QALD7 can be downloaded here »

Getting Started with Knowledge Graphs – metaphacts Tutorial at ESWC 2017

ESWC 2017 May 18, 2017 - metaphacts founder and CEO Dr. Peter Haase will be holding a tutorial at the Extended Semantic Web Conference (ESWC) taking place in Portoroz, Slovenia on May 28-June 1. The ESWC is a major venue for discussing the latest scientific results and technology innovations around semantic technologies.

The tutorial "Getting Started with Knwoledge Graphs" will be held on the afternoon of May 29th and will cover the fundamentals of knowledge graphs and present specific examples of application areas. In hands-on exercises attendees will get the chance to experience metaphacts' knowledge graph platform firsthand and create a small, but real knowledge graph, covering the entire lifecycle including integration and interlinking of existing sources, authoring, visualization, querying and search.

Geomarketing driven by Knowledge Graphs - metaphacts at CeBIT 2017

CeBIT 2017 March 15, 2017 - As a member of the GEISER consortium, metaphacts will be exhibiting and showcasing its solution for data-driven geomarketing at CeBiT 2017, held in Hannover, Germany on March 20-24.

As part of the GEISER project and in collaboration with YellowMap, the Frauenhofer Institute for Intelligent Analysis and Information Systems and the University of Leipzig, metaphacts has developed an innovative system where geospatial data is used as raw material for intelligent, location-based services. The system delivers great promise for supporting small and medium-sized businesses and retailers in linking sensor data with Social Media data, Open Data, forums, websites and internal customer data, so as to improve their advertising and marketing strategies.

A concrete use case where Twitter data is abstracted and contextualized through the integration with the Wikidata Knowledge graph, so as to enable businesses to formulate precise information needs and conduct accurate queries, will be showcased at the German Federal Ministry of Economic Affairs and Energy booth at CeBIT. In this particular use case, small and medium-sized businesses are able to identify the events taking place in a given region and during a particular timeframe, and, thus, can create targeted advertising campaigns for these events.

To learn more about metaphacts and our solutions, visit us at CeBIT at booth C40 in hall 6! We look forward to seeing you there! To schedule a meeting during the event, please send us an email at This email address is being protected from spambots. You need JavaScript enabled to view it.

ResearchSpace Public System

ResearchSpace Public System

January 23, 2017 - metaphacts and the ResearchSpace consortium recently released a public system showcasing the powerful semantic search functionalities delivered by the ResearchSpace platform.

ResearchSpace, a British Museum project funded by the Andrew W. Mellon Foundation, builds on the metaphactory platform and leverages Semantic Web technologies to deliver a comprehensive solution for cultural heritage research.

The public system can be reached at It features a preview of the tools delivered by the ResearchSpace platform and will be extended in the future to make additional tools publicly available, such as Geo-search, semantic clipboarding, semantic annotation and assertion representation. A guided tour introduces users to the system and supports them in performing and visualizing a complex query using the intuitive ResearchSpace search interface.

“We see great potential for ResearchSpace to help tackle the challenges encountered by researchers in the cultural heritage domain and are really excited to have this public system provide users with a first taste of what our solution can do”, commented Dr. Peter Haase, CEO at metaphacts.

Blazegraph GPU promises extreme scaling and is 100x faster

Blazegraph GPU March 29, 2016 - The memory bandwidth advantages of GPUs provide a great way to accelerate data-intensive analytics and graph analytics in particular. Graph query and iterative graph analytics has demonstrated significant speedups over CPU-based approaches. metaphacts contributed to the development of Blazegraph GPU - a system that exploits the main-memory bandwidth advantages of GPU in order to provide extreme scaling that is 100s of times faster and 40X more affordable, 10,000X faster than disk-based, and 100s of times faster CPU main memory-based approaches. This technology is called Mapgraph and it is being productized into the Blazegraph family of products as Blazegraph-GPU and Blazegraph-DASL using familiar high-level APIs for graphs.
